VEHICLE-WHEEL RIM.

SPECIFICATION forming part of Letters Patent No. 593,268, dated November9, 1897.

Application filed October 11, 1 8 9 5.

To all whom zit may concern:

Be it known that I, CHRISTIAN ANDEREGG, a citizen of the United States,residing at Indianapolis, in the county of Marion and State of Indiana,have invented certain new and useful Improvements in Vehicle-Wheel Rims,of which the following is a specification.

This invention relates to the form of the joints by which the ends ofwooden felly parts are united in the manufacture of wheel-rims such asare used in bicycles; and it consists in a peculiar formation of suchjoints whereby a very firm and durable union is effected, all as. willbe hereinafter more particularly described and claimed.

Referring to the accompanying drawings, which are made a part hereof andon which similar letters of reference indicate similar parts, Figure 1is a side elevation of a bicyclewheel having a rim constructed inaccordance with my said invention; Fig. 1 a fragmentary side view of aportion of the rim at the joint, on an enlarged scale; Fig. 2, a planview of the inner side of the rim at the joint as seen from the dottedline 2 2 in Fig. 1; Fig. 3, a similar View of the outer side of the sameportion of the rim; Fig. 4, a View similar to Fig. 2, except that theparts are slightly separated; Fig. 5, a transverse sectional view on thedotted line 5 5 in Figs. 1, 2, and 3; and Fig. 6, a view similar to Fig.4, except that the center cut is shown at somewhat of an angle with thegeneral direction of the wheelrim instead of parallel therewith.

All parts not specifically otherwise described are or may be of anyordinary or desired construction.

The wheel-rim A is formed of one, two, or more pieces which are broughttogether and are united at the ends by means of the surfaces provided bycutting said ends in the form shown. The cuts by which this form isproduced are preferably a straight vertical cut central of the rim partand parallel with the face of the wheel and two shearing cuts leading infrom the sides of the rim to said straight out. At acute anglestherewith, as shown, the several cuts extend through the rim in thedirection of its thickness, the side cuts being somewhat tapered or outunder, making a spliced joint, which when the parts are forced togetheris so formed upon the outside as not easily to sliver up in case of theglue loosening its hold.

Serial No. 565,385. (No model.)

As shown in Fig. 6, the central cut may be slightly angling,if desired,which gives somewhat of an overlapping of the resulting tongues a,instead of a surface parallel with the sides of the tire, andconsequently in line with the direction of strain, whenever there is anytendency to pull the rim portions apart. The points which are reached bythe ends when forced together are clearly indicated by the dotted linesin Figs. 4 and 6.

As shown in Fig. 2, the side cuts are so positioned that they comenearly together in the middle, where they approach each other, and theymay be so positioned as to blend into each other at that point. On theopposite side, however, as best shown in Fig. 3, they depart aconsiderable distance from each other,forming the points or tongues o.This form is pro duced by having the shearing cuts diverge in differentdirections from the plane of the rim.

Having thus fully described my said invention, what I claim as new, anddesire to secure by Letters Patent, is-

1. A wheel-rim composed of portions joined by having their ends cut tofit together, the cuts consisting of a central cut extending through therim in a plane substantially parallel to the face of the wheel, and twoside cuts'extending to each side of the rim from said central cut and atan angle thereto, the planes of said cuts being at an acute angle to theplane of the central cut, substantially as set forth.

2. A wheel-rim composed of port-ions joined together by having theirends cut to fit together, the cuts consisting of a central cut extendingthrough the rim in a plane substantially parallel with the face of thewheel, and two side cuts extending to each side of the rim from saidcentral out at an angle therewith and also at an angle with the face ofthe wheel, or cut-under, the planes of said side cuts being at an acuteangle to the plane of the central cut, substantially as set forth.

In witness whereof I have hereunto set my hand and seal, atIndianapolis, Indiana, this 8th day of October, A. D. 1895.
